Recommanded Product: 19777-66-3. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: (S)-Propane-1,2-diamine dihydrochloride, is researched, Molecular C3H12Cl2N2, CAS is 19777-66-3, about Unprecedented Asymmetric Epoxidation of Isolated Carbon-Carbon Double Bonds by a Chiral Fluorous Fe(III) Salen Complex: Exploiting Fluorophilic Effect for Catalyst Design.
The first asym. epoxidation of isolated carbon-carbon double bonds by a chiral salen complex using ubiquitous Fe(III) as a center-metal was described. By simultaneously introducing fluorous tags and tert-Bu groups into the ligand of the salen complex, asym. epoxidation was achieved. The fluorous tags act as both the electron-withdrawing groups, to improve the catalytic activity for oxidation, and the driving force to form a unique asym. stereo environment. Crystallog. anal. of the complex revealed that the catalyst has a distinctive umbrella structure based on intramol. fluorophilic effect. This is the first example of asym. catalytic space construction that exploits fluorous space-interaction of neighboring fluorous tags.
After consulting a lot of data, we found that this compound(19777-66-3)Recommanded Product: 19777-66-3 can be used in many types of reactions. And in most cases, this compound has more advantages.
